    i am using stoch ea from your website. what is te different between the free dwnlds ea compare to paid ones? if there there is a difference please advise me which one i should buy to maximize profit, ihave lost big time on forex.

    1. Yannick says:

      The basic version has fewer features in it. You’ll find all features the advanced and pro versions include on its product page. If you’re happy with the basic version and make some good trades, you should consider upgrading to the advanced or pro version.

    I wanted to check some of your free EAs using Metatrader 4.
    No trades are initialised on any time frame.
    I’m running Metatrader 4 on a Linux system (Ubuntu 16.04 LTS) via Wine
    Is it possible that the “stdlib.ex4” that you refer to in your EAs dependencies-window cannot be accessed because on my system the path for it is:
    /home/johann/.wine/drive_c/Program Files (x86)/QTrade-FX MT4 Setup/MQL4/Libraries
    Could this cause the/a problem?
    Think about it – a solution would be most welcome and could lead to purchases if your products are helpful.
    I couldn’t find any e-mail-address on your website.

    1. Yannick says:

      No, the stdlib.ex4 should not be the problem. I’m also using wine on 16.04 and it just works out of the box. Maybe try to reinstall the terminal?

    1. Yannick says:

      Please double check if you placed the EAs into the mql4/experts folder. Otherwise contact the support and provide as much information as possible, included screenshots.

  9. Kyi Nyunt says:

    Hello, How can I close the EA?

    1. Yannick says:

      To remove an EA you only have to delete the file on your computer.

  10. Peter says:


    I downloaded the EA, however when I download the file to my computer and go ahead and open it, it shows me a very weird code which doesn’t work when I try to compile it. Even when I follow the manual, the document is not there.
    Whilst, other mt4 codes do show up.

    Greetings, I hope you can help!

    1. Yannick says:

      You do not have to open the file or compile it. Just copy and past it in the right folder.

  11. Dinesh Kumar says:

    I installed the EA in correct folder and just changed the TP from 50 Pips to 10Pips. Apart from that, i have not changed any settings. No trades have been opened yet. Please help me..

    1. Yannick says:

      It could be because of the spread filter. If you EA has a spread filter (max spread), increase it and try it again. I recommend you to test it on the M1 timeframe because it generates the most signals.

  12. Srinivasan G R says:

    Hi Yannick,

    I downloaded the free version of HA smoothed today and installed the same in my demo MT4 a/c.
    I’m able to view the EA in the Navigator tab. But, I’m unable to drag or double click it on to a chart. What could be the problem?

    1. Yannick says:

      One of the files (Heiken Ashi Smoothed.ex4) in an indicator. You have to install it in the MQL4/indicators folder.

  13. arvinraj11 says:

    hello Yannick.. Is that we have to click Allow DLL Imports..??

    1. Yannick says:

      No, you do not need to allow DLL import for my EAs.

  14. Sally Underwood says:

    Hi. I cannot install the EAs. I copied them into the MT4 Experts folder and reopened MT4 but they are not there.

    1. Yannick says:

      Please doublecheck if you installed the EAs in the right folder.

  15. nan says:

  17. luca says:

    what are the MA in MA cross that i bought : otherwise i can not instal it

    gr luca

    1. Yannick says:

      The “MA Cross EA” does not draw any indicators to the chart. You have to put them on your own to the chart.

  19. jobumarou says:

    Also, I purchased the ichimoku EA and I’d like some modifications to be done for better performance according to my strategy. Will that be possible?

    1. Yannick says:

  21. Aghogho Oyibo says:

    I purchased the super trend just now. I’ve tried installing it but it’s not reflcting on my platform. What should I do?

    1. Yannick says:

      You have to put the SuperTrend indicator in the Indicators folder and not in the Experts folder.

  22. Aghogho Oyibo says:

    Do you offer VPS for your EAs?

    1. Yannick says:

      No sorry, I don’t offer VPS.
